Yeah ignition timing is big in tuning.

Also, make sure you're running the proper heat range spark plugs.

Well I decided that it was in my best interest to not try to sleeve/rebuild my other motor, 2 failures in a year tell me that there is some voodoo beyond my reasoning that wont allow it to run...lol. So here I have started with a new "fresh off the boat" S13 SR20DET. It is going to be a fairly stock swap at first. I've replaced every gasket I've removed/touched, put a new intake manifold on, powdercoated the valve cover, got new belts, and put on my old T28 turbo setup. Im only going to run like 10psi on it with stock fuel system for now.

Once I am confident in the motor, I will send off my ECU to Jim Wolf Tech and have them flash it for my Z32 MAF, 740cc injectors, and increased boost up to 18psi. That setup should be good for around actual 300whp. Im just now getting the motor together up at the shop. Its taking a while, because I am doing it right, replacing gaskets, and making sure everything is clean before installing. I got all the wiring finished, and should have the motor totally done within a day or two. Here is the progress so far on the motor, I will keep this thread updated until it is back on the road! Thanks for looking, cant wait to fucking get back in my car!!!

S13 Blacktop (ignore the valve cover...and turbo, it never ran with that turbo, it was just the motor he bolted it to once it was imported to show off the turbo kit, so he could sell it)

Cleaned it up a bit:

Stripped the VC for powdercoat:

Got a new intake:

Installed my turbo:

Almost there!

looks good man, hope everything goes well this time

Bbsalexaz · 08-16-2011, 12:34 PM

stop getting it chipped. thats going to be a rich tune that won't really get anything done for ya. I would recommend buying nistune, and the board required to tune the ecu. then take the car to a tuning shop.

You find me a competent tuning shop within 250miles of my house, and I'll do it.

I dont care about peak power, I need dead solid reliability.

Datspar · 08-17-2011, 10:28 AM

Nice motor, and I'll take the girly

boost addict · 08-17-2011, 11:54 AM

Bbsalexaz is right, I'm pretty sure I've mentioned nistune to you before. I just got mine and for the 300 bucks it's a great price for what it does. I think if you have to go 250 miles then do it, it'll be worth it

If that is what your looking for, go get a proper tune. Any reputable shop can tune the car to run in a reliable manner without pushing the envelope.

Even if you have to take a trip, in the long run it will be worth it!

Thats what Im saying is that there are no reputable shops anywhere near our town thaT I trust to tune it.

I've talked to enough people to feel confident in my decision to go JWT.

EJ8 944 · 08-18-2011, 11:29 AM

Have you thought about flying in someone to tune your car? Long as you can find a shop you could rent some dyno time from.

BlackZenkiS14 · 08-18-2011, 11:33 AM

That is serious money. Like nearing 1k, plus the cost of the tuning software, and plus the cost of the dyno time.

This is a street driven, stock block car, on a T28 lol, I dont think all of that is necessary to achieve a safe solid tune!

BlackZenkiS14 · 08-22-2011, 11:41 AM

Got it in, and it runs!

Without a doubt 11.5 and lower is 'more safe' but 11.7-12.0 on a stockish setup is plenty fine.

Sure Nistune is capable of tuning it, but if the end tuner is an idiot, or incapable, it's no better than the SAFC in regard to being safe (not in comparison).

The thing is, is it that much better than a JWT or Enthalpy tune? Hard to say...the JWT and Enthalpy tunes work great, and are proven to be more than safe most 'streetable' power levels....not to mention turn key/oem like functionality. Can't beat that. Don't relate random reburnt 'tunes' to a one off tune from either JWT or Enthalpy.

What's to say the 'tuner' is any better than a JWT setup? If anything there are COUNTLESS cars on here with 'custom tunes' that make less power and drive shittier than a quality rom rune. Very few tuners are worth their weight....and that's across the board/all brands.

Yes, since his stock engine needs a 1000 dollar tune

Yep! Thanks for the support Cody. I’m really taking as much of your experienced advice to heart as I can with this new build.

I am currently just on the S14 T28, with the Isis intake, stock fuel, stock ecu, and stock MAF. I’ll get some more pics of everything tonight. Gonna work out some of the finer kinks tonight at the shop I hope, and have it on the road solidly. I plan on running it like this for a month or so, to make sure everything else is trouble free.
I have my Z32 MAF, and 740CC injectors sitting in my room just waiting to get funds together for my JWT ecu. And then hopefully upgrade to the .64 2871 in the spring time!

All I hope for is reliability, streetability, and 325whp. In the meantime, once I get the 740cc injectors and Z32 MAF on with the JWT, how much boost can I safely run on that setup with the S14 T28?

*fliprayzin240sx* · 08-22-2011, 07:15 PM

With your current track record...leave it at stock boost. No need to crank up the boost till you get a tune. Last thing you need is cranking it up and that shit starts knocking.

Thats the plan. I wont touch a single thing until I have my JWT.

Although, this motor might be bad, so I might be a while off from anything at this point
